How to Fix / Troubleshooting
Safety first: Unplug the microwave before removing any covers.
Steps:
- 1. Listen for fan operation: When starting a convection or combination cycle, listen for the convection fan at the rear. If it does not start or makes grinding noises, there is a fan issue.
- 2. Inspect rear vents: Check for obstructions at the rear convection outlet. Remove any debris.
- 3. Internal inspection (experienced DIYers): Remove the cabinet and locate the convection fan motor. Check that the blades spin freely by hand and that no insulation or wiring is contacting the blades.
- 4. Check wiring: Ensure the fan motor connector and any tachometer feedback wires are secure.
Next steps: If the fan is seized or the tachometer sensor is faulty, replace the convection fan motor assembly.
